Hey, when it comes to mobile, I develop them in pure Objective-c for iOS, and pure Java for Android. I use tools provided by both compagnies. So yeah, I do the jobs twice, but I think it's ok.

Anyone have feedbacks coming from what I do to something like RubyMotion or Xamarin? These solutions sound very interesting, but I've yet to try them. I think I'm too attached to my Objective-c and workflow.

Also, is there peoples who originally used RubyMotion or Xamarin and went to use OC and Java?
